Add SSL implementation from Supermium 121

[JoachimHenze]

On Windows XP the Chrome browser typically uses ciphers from Windows schannel.dll implementation. Unfortunately those are not maintained by Microsoft anymore, and therefore the regular Chrome versions, including your Chromium XP v49 are not able to display specific websites which do use newer ciphers like the Elliptic curve ciphers ECDSA* and so on.

As a test the following website can be used:
https://html5test.opensuse.org
This is just one of many many examples.

It will fail to render the page with
ERR_SSL_VERSION_OR_CIPHER_MISMATCH
on Chromium-XP v49 on WinXPSP3.

but on Supermium 121 (Chromium-fork) (and all Firefox based browsers also) the site will load fine.
Firefox does always bring its own SSL implementations. But the Chromium-based Supermium 121 browser https://github.com/win32ss/supermium , which is open-source, also managed to overcome that bug by adding its own SSL implementation.

Request is to do the same for your Chromium XP.

You may ask: Why not simply using Supermium 121 instead? The answer is that your Chromium v49 is much more lightweight on resources, faster and much more stable (atm).

I do assume that https://github.com/win32ss/boringssl may be of use.
